One of my favorite songs by the duo Elenowen is called 'Losing the Lonely'. There's a verse that says: "Long shot, we went against the odds in a game you'll never win, if you never go all in..."
I think the ability to "go all in" develops as you mature and can mean different things at different times in your life. Sometimes it means having the courage to try out for a sports team or sing a solo in front of a crowd. Other times it means changing your entire career or choosing to walk away from a dysfunctional relationship.
Going all in requires you to be brave. Being brave means discovering what you need to do and doing it despite your fears. The path we forge ultimately influences our character and the lives of those we touch.
Life is both uncomfortable and exhilarating. That's why we're here. To learn and grow. To develop meaningful relationships. To remember who we really are and to whom we belong.
